Has anyone ever used the circuit repair kits? The type where you can replace a PTH or SMT pad that has been lifted or damaged? It appears that you just select a pad, trace or whatever needs replacing from a panel and heat or glue it onto the board.

So I'm the only one that's had crappy piles of silkscreen between pads?

We had a supplier that put a [fuzzy and of variable height) line of ss between all chip R and C pads. Of course we were in low cost mode and had purchased a year's worth of boards.

We are assembling double side pcs reflowing (smt) on top and by wave on bottom. After first step (smt) we dispense glue on the bottom side putting one or two glue dots under small components and we cure in oven before wave. After wave soldering we f

Frank, Don't know about point 1 but if they don't fall off I don't worry about it. If they do fall off it's generally because someone has mishandled them before the wave, like shoving them into racks and the like. If they have fallen off and you can'

I concern about the Through Hole soldering as well. Currently, we have encountered some problems of Multilayer from Through Hole soldering. The root-cause is probably related to PCB Finish, machine setting, Thermal relief Pad or hole and something e

You will need to prepare the component and site for rework. Using solder wick remove the solder from the pad site and the component balls. You can also use a heated Vacuum desoldering tool. To reball we have been using Winslow Automation reballing ki

Ashok: Well, your customer probably has a good reason for wanting you to send them boards without holes in the solder mask. What is their goal for the mask capabilities after you get do reworking the boards? * Cosmetic surface coat? * Performance t

| Can plcc's be glue on the a board if not why? | Ron, The biggest problem you have with PLCC's is the hieght of the base of the component from the board, if you can get a glue dot high enough then yes you could do it. Probably the best method is d
